Thyristors are a semiconductor device commonly used in power electronic applications. SCRs or Silicon Controlled Rectifiers, are a type of thyristor wherein the current flow is switched by a voltage applied between the cathode and the anode. The VS-111RKI80 SCR is a three-terminal device with two gate terminals and an anode terminal. The power dissipation of the device depends on its specific application but generally ranges from 50 to 400 W.

The application field of the VS-111RKI80 SCR is wide and varied, ranging from a broad number of consumer and industrial applications such as electric motor control, lighting control, motor speed control and motor start-up. One of the most commonly used applications for the VS-111RKI80 is the contactor for controlling the power in large inductive electric motors, as well as for industrial electric arc welders and energy saving applications. The device can also be used in tandem with other SCRs to perform synchronized AC rectification and power coupling.

The working principle of the VS-111RKI80 SCR is relatively simple; when the anode to cathode voltage (VAK) is applied, a small gate current (Ig) will flow, which will cause the device to turn ‘on’. This current is usually a few mill Hams and can be provided by a variety of sources, such as a control signal, thermistor or controller. The device will remain ‘on’ until the anode current reaches the holding current, at which point it will turn ‘off’. The device will also turn ‘off’ if the gate signal is removed.

The VS-111RKI80 SCR is a well-proven, reliable device which can be used in a variety of applications. Its low gate triggering current, high blocking voltage and low on-state voltage make it well suited to a number of applications, such as motor speed control, motor start-up or contactors in high power inductive loads. Its simple operation and easy connection makes it a favourable choice for many applications.
